direction arrow, but the position don't change.

Hi,
do you have a device called "/dev/input/mouse0"?

If not then your kernel was built without input device support

check that in your kernel ".config" the INPUT_EVDEV is set

you should enable it under:

-> Device Drivers
-> Input device support
-> Event interface

regards.
Haithem.
